Burgess got the nod for the role in the Four Nations with Sean O’Loughlin injured.
“Not at all, I was completed not worried about it,” he said.
“Obviously I was gutted that Sean O’Loughlin couldn’t be part of the team. But I’m 100% behind Sam.
“He inspires people with what he does, with his actions and I can’t wait to play alongside him again.
“We’ve been roomates this first week and everything’s great.
“We’re really good mates. He’s been one of the best forwards in rugby league since how long he’s been playing the game really.
“I think he’s back where he belongs and it’s great for rugby league that we’ve got him back.”
Graham was the victim of a spear tackle on Saturday and was forced from the field.
But the Bulldogs prop is confident he will be fit to play against New Zealand this weekend at Huddersfield.
“I’m alright,” he said.
“I think I have to do a head test, a concussion test, this week but I’m feeling alright. I should be fine.”
